TEAMGROUP HIGH Endurance 64GB Micro SDXC UHS-I U3 V30 4K 100MB/s (Designed for Monitoring) Memory Card, 4K & Full HD Video Recording TTUSDX64GIV3002

Good deal. I got them for my dash cams and Wyze cams. One of my Wyze cams was being picky and wouldn’t accept several other SD cards. I was happy when this one worked.

This is working great in my Tapo C325WB camera. No issues whatsoever. We get a ton of motion alerts since we face a road, but the card is holding up great.

Used these sd cards on our Wyze outdoor/indoor Cam Pan V3 video cameras. Work like a charm and at a great price! Work as good as the name brand which would cost a lot more!

works well with my dash-cam so far.... good purchase

I got these to put into security cameras. After a year the cameras ceased functioning but these are still going strong, I just don't have anything to really use them in.

Best bang for your buck with Wyze cameras. Nothing beats the price and year later, they're still going strong. Perfect price for a pack of 3.

I have never bought any TeamGroup stuff but I hear good things so decided to try them out. I have been setting up security cams and these being so cheap made them perfect choice for me. What I didn't expect was how much faster than my standard Samsung card it was. These are so fast I decided to keep one for my phone and ordered another to replace it.Nice job TeamGroup, I am impressed. I did full capacity test like I always do with sdcards and all is good!I recommend these cards highly, so cheap but yet so fast!

Update: After more testing, I have discovered that the problem with these cards is that each time you start writing a file, there is chance that you may see a delay of up to 12 seconds before the card finally starts writing data. Once the data finally starts flowing, the cards are actually very fast, maintaining 80 MB/s write speeds in a typical SD card reader. Unfortunately, this is why they fail to function properly in my dashcams, as it seems that the dashcam is constantly switching back and forth between writing to 3 different files for the 3 different cameras. Every time it switches which file is being written to, there's a chance for it to encounter the up-to-12-seconds delay where ZERO data is being written, causing the dashcam to malfunction. A dashcam which is unable to record constantly is not protecting its driver if something happens during the missing gaps of time. Team Group has replied to my initial review and suggested that I initiate an RMA to get them replaced under warranty. If I do end up receiving replacements, I will add another update after thorough testing.Original review: I bought the 3-pack of 256GB High Endurance cards. These cards are sold with the V30 and U3 ratings, both of which are supposed to guarantee a continuous write speed of 30MB/s to support 4K video recording. I attempted to use these cards in 2 different dashcam models, one which records at 6.7MB/s and the other at 3.7MB/s. Unfortunately, they couldn’t handle it. They lag behind and cause the less demanding dashcam to crash/reboot, missing chunks of time ranging from 5-45 seconds long. In the more demanding 3-camera dashcam (which also runs quite hot) the cards sometimes fail to record AT ALL for hours at a time. When this brand of cards are on sale, they can be the best deal for general purpose storage, but I cannot recommend the TEAM High Endurance cards for video recording. Additionally, I have a TEAM PRO+ 256GB card, and that card can JUST keep up with the 3.7MB/s dashcam, but it chokes in the 6.7MB/s one. So I can’t recommend it either.Based on firsthand experience I can recommend:Samsung Pro PlusSamsung Pro EnduranceSanDisk ExtremePNY Premier-X
